Underworld

(Series 15, Episodes 17-20)

Summary: Let the sky falllll!  Are you sure you’re not in the Matrix?  ‘Cause those tunnels don’t look real to me…  The Tardis materialises on a Minyan spaceship which is off on a quest to find another spaceship full of missing race banks, after the Time Lords meddled in their society, leading them to destroy their home planet in an all-consuming civil war.  Turns out, the missing Minyans are in a bit of a pickle, enslaved by a sentient computer to dig rocks in underground tunnels.  The Doctor confronts the computer, steals the race banks and makes his escape.  And in the end, sometimes two cigar-shaped bombs are just two cigar-shaped bombs.

Watch it because: The music when they’re floating is just delightful.
